Pay attention when selecting rubber flex joints

Rubber flex joint has numerous ground bolts on it, there are long ground bolts and short ground bolts, there are also many nuts, we come to master the actual effectiveness of such ground bolts: from the photo of the rubber flex joint we can see that there are lengths of various ground bolts, some ground bolts also contain several nuts on the side, technical engineers say to you how to use the rubber flex joint, the first to master the rubber flex joint The application characteristics of the loose-fitting expansion device installed in the pipeline after the twisting of the nut elastic sealing ring, in the effect of the nut screw cap tilt degree of each other, tightly pressed in the outside of the pipeline to play a sealing and coupling effectiveness. When the ambient temperature changes the pipeline can be in the middle of the interface expansion type, when the foundation sinks, the pipeline can be tilted, and to ensure that the seal does not leak, and thus has a fully automatic compensation purpose.
1 . Corrosion resistance to be good: chemical plants with rubber flexible joints sealing ring and inside the corrosion-resistant raw materials have to be made of materials, the outside stainless steel plate using stainless steel plate, as far as possible to enhance the corrosion resistance of rubber flexible joints.
2 . The use of rubber flexible joints: rubber flexible joints are the original characteristics of the positioning role, the application of foot bolts to lock the amount of expansion type, so that the rubber flexible joints in the scope of the expansion type, the level of ensuring the operation of the pipeline.
3 . Withstand capacity to be good: If the capacity is low, the chemical manufacturing industry in the application of rubber flexible joints transport, there is a possibility that the rubber flexible joints used for too long or other problems make it crack, resulting in leakage.
